Description

Technical Field

[0001] This utility model relates to the field of heating equipment, and in particular to a gas-fired heating device. Background Technology

[0002] In northern China and other regions where winter temperatures are relatively low, heating systems such as underfloor heating, electric heaters, or air conditioning are needed to ensure a comfortable environment. However, in remote areas or rural environments abroad, electricity supply cannot be guaranteed after snowfall in winter, requiring generators and other equipment to boost the power supply. In such cases, gas heating becomes the only option.

[0003] For gas heating devices, most existing designs directly discharge exhaust gas, which wastes some heat and is not energy-efficient or environmentally friendly. This may not meet the combustion efficiency, energy-saving and environmental protection requirements of some countries for gas heating devices.

[0004] Therefore, there is a need for a gas heating device that can reduce energy consumption and meet energy conservation and environmental protection requirements by setting up an exhaust gas emission mechanism and maximizing the utilization of the heat of the exhaust gas. Utility Model Content

[0005] The main objective of this invention is to provide a gas heating device that reduces energy consumption and meets energy conservation and environmental protection requirements by setting up an exhaust gas emission mechanism and maximizing the utilization of the heat from the exhaust gas.

[0006] This utility model proposes a gas heating device, including a housing and a combustion mechanism, an exhaust gas emission mechanism, an air intake mechanism and an external circulation fan disposed within the housing;

[0007] The air intake mechanism includes an air intake mechanism body and an internal circulation fan. One end of the air intake mechanism body is connected to the air inlet of the internal circulation fan, and the other end of the air intake mechanism body is L-shaped.

[0008] The combustion mechanism includes a combustion mechanism body and a burner disposed within the combustion mechanism body, wherein the air inlet of the combustion mechanism body is connected to the air outlet of the internal circulation fan.

[0009] The exhaust gas emission mechanism includes an exhaust gas emission mechanism body and an air inlet / outlet head. The air inlet / outlet head includes a central air outlet and an annular air inlet surrounding the central air outlet. The annular air inlet is connected to the air inlet of the air intake mechanism body. A central air outlet head is provided behind the central air outlet. The rear side of the central air outlet head passes through the air intake mechanism and is connected to the exhaust gas emission mechanism body. The air inlet end of the exhaust gas emission mechanism is connected to the air outlet of the combustion mechanism.

[0010] The external circulation fan drives air to enter from one side of the casing, and after passing through the combustion mechanism, the exhaust fan, and the air intake mechanism, the air exits from the other side.

[0011] By incorporating an exhaust gas emission mechanism, the incoming air can be heated and further heated before being discharged, thereby improving the overall thermal efficiency of the gas heating system.

[0012] Preferably, the exhaust gas emission mechanism body includes an outer emission cavity and an inner emission cavity, wherein the inner emission cavity is disposed inside the outer emission cavity and is fixedly connected to the inner surface of the outer emission cavity adjacent to the combustion mechanism;

[0013] The air outlet of the combustion mechanism passes through the outer exhaust cavity and connects to the air inlet of the inner exhaust cavity. The air outlet of the inner exhaust cavity is provided on the side of the inner exhaust cavity away from the central air outlet, and the outer exhaust cavity and the inner exhaust cavity are connected through the air outlet of the inner exhaust cavity.

[0014] Preferably, the combustion mechanism further includes at least one exhaust pipe, and the combustion mechanism is connected to the exhaust gas emission mechanism through the exhaust pipe.

[0015] Preferably, it further includes a water outlet mechanism, which includes a water outlet head, a water inlet head, and a connecting water pipe. The water outlet head and the water inlet head are disposed on the housing and are connected through the connecting water pipe. The connecting water pipe is arranged around the outside of the combustion mechanism and can heat the water in the connecting water pipe through the combustion mechanism.

[0016] Preferably, the connecting water pipe is made of metal.

[0017] Preferably, an air inlet / outlet grille is provided on the side of the housing.

[0018] The beneficial effects of this gas heating device are as follows:

[0019] By setting up an exhaust gas emission mechanism, the exhaust gas can be used to preheat the air intake of the intake mechanism, and during external circulation heating, the exhaust gas emission mechanism can be used to heat the air intake of the casing, thereby improving the thermal efficiency of the gas heating device.

[0020] By setting up a water outlet mechanism, hot water can be supplied to the gas heating device.

[0021] In actual use, when the user selects water output, the gas heating device will stop the operation of the external circulation fan to ensure that the combustion mechanism heats the connected water pipes as much as possible, thereby ensuring that the temperature of the output water meets the requirements.
